The laboratory disperser is built to handle different mixing and dispersion tasks within a single unit, making it suitable for formulation testing and small-batch trials. It combines mixing, grinding, and dispersing functions, allowing users to switch between different working heads depending on the process. With a wide speed range and adjustable control, it supports detailed parameter testing and helps generate reliable data for scale-up. Its compact design and adaptable configuration make it suitable for applications in coatings, inks, pigments, food, daily chemicals, and nanomaterials.

New Materials
- Multiple function in one machine
Combines mixing, grinding, and dispersion functions, allowing different processes to be completed by changing the working head, reducing the need for multiple machines. - Wide and precise speed control
Uses frequency conversion or digital PID control to provide stepless speed adjustment up to 10,000 rpm, with direct speed display for accurate operation. - Adjustable lifting system
Hand-operated lifting mechanism with a stroke of 200–300 mm allows flexible positioning and easier handling during experiments. - Interchangeable working heads
Available with multiple dispersing and grinding head sizes, allowing selection based on material characteristics and testing requirements. - Flexible batch capacity
Handles volumes from 200 mL to 10,000 mL, covering both laboratory-scale testing and small-batch production. - Material compatibility and hygiene
All material-contact parts are made from SS304 or SS316L stainless steel, supporting corrosion resistance and meeting requirements for chemical, pharmaceutical, and food-related applications.
- Efficient and stable motor performance
Equipped with a permanent magnet brushless DC motor or variable frequency motor, providing stable operation, high torque, low noise, and reduced maintenance due to the absence of carbon brushes. - Secure and stable operation
The clamping device helps fix the container in place during operation, improving safety and reducing vibration during high-speed dispersion. - Optional cooling support
Some models can be equipped with jacketed containers, allowing cooling water to control temperature rise during processing.
